64/128 VIEW

TOM hie espeS.[s-15

or some time we’ve been think-

ing about providing a showcase

for 64 and 128 artists, a place to

display their computer master-
pieces. Beginning with this month’s
Gazette Disk, we'll be publishing
some of your best submissions in
what we call “Gazette Gallery.”

By selecting COMPUTE’s Ga-

zette Gallery Viewer from the disk
menu, you'll see some of the best

64/128 artwork available in a slide-
show format. Each piece will be pre-
sented just as the artist created it and
as it was meant to be seen, on a com-
puter monitor.

We pay $50 for each picture that
we select for display in “Gazette Gal-
lery.” From those selected, we’ll name
one Picture of the Month and award it
an additional $50. So if you have orig-
inal computer artwork that you’re
proud of, send it in. We want to see
your best work. Pictures may be in
Koala, Doodle, or any other popular
format. Send no more
than five entries per
disk per month to Ga-
zette Gallery, COM- |
PUTE Publications, 324
West Wendover Ave-
nue, Greensboro, North
Carolina 27408. Be sure
to put your name, ad-
dress, and daytime tele- |
phone number on your
disk. And enclose a self-
addressed, stamped disk
envelope if you want
your artwork returned.

For years we’ve
done our best to provide
Gazette readers with =:
outstanding type-in pro-
grams for the 64 and
128. Whether they’re
games, programming
utilities, or productivity
or educational pro-
grams, we try to publish
a variety of the best pro-
grams submitted to us
each month.

Occasionally we
come across programs

GEOFFREY GOVE

we like but which are just too large to
offer as type-ins. By adding so many
outstanding features, the programmer
has made the program too big. The
listing would run for pages and pages,
and it would take weeks for the aver-
age reader to type it in. In the past
we've been forced to reject these pro-
grams, but now we’ve found a way
around this problem.

Each month on the Gazette Disk,
we're presenting these larger programs
and certain others as bonuses. We
started with the October disk with a
program called geoGammon. This
computer version of backgammon for
GEOS and GEOS 128 was simply too
large for us to offer as a type-in, but
we felt it was an excellent program
that our subscribers would appreciate.
The game, with complete documenta-
tion, appears only on the October
disk. There’s nothing to type in; it’s
ready to run. Two other programs,
Multi-Color Lister and 64-Shell,

rounded out last month’s bonus pack-
age on the Gazette Disk.

This month’s disk features two
bonus programs. Bastion is a futuris-
tic, one- or two-player arcade-style
shoot-em-up in which your spaceship
tries to blast its way through layers of
rotating shields. Eye Catcher isa
scrolling text utility that’s handy for
announcing special events and the
time they’re scheduled.

Speaking of utilities, we’ve no-
ticed a shortage of them recently.
Most of our recent submissions have
been games. Many of these are excel-
lent, but the 64 and 128 are more than
just great game machines. So if you
have a programming utility—a piece
of software that helps out around the
house or office or is educational in na-
ture—we’d like to look at it. We espe-
cially need programs for the 128 that
take advantage of its unique features.
Now’s a great time to send your best
original programs to our submis-

sions reviewer.

In an effort to allot
more magazine pages to
type-in programs, we
won’t be printing The
Automatic Proofreader
and MLX in every issue
of Gazette as we have
done in the past. These
programs will still be
used, however, to help
readers enter the pro-
grams correctly. Copies
of these handy programs
can be found in back is-
sues of the magazine,
and we'll print them
whenever space allows.
If you don’t have access
to back issues and you

| need a copy, we'll be
glad to send you a free

| listing. Simply write to
Typing Aids at the ad-
dress listed above. Be
sure to enclose a self-
addressed, stamped en-
velope and remember to
mention which program
listing you need. io]

Data East (1850 Little Orchard
Street, San Jose, California
95125) has scheduled for release
North & South ($24.95), a Civil
War strategy game for the 64.
Three levels of difficulty and
four stages of battle offer hours
of play as you control armies
and territories, launch attacks,
and maneuver your troops
through conflict, storms, and
even Native American attacks.
Choose the perspective of
either a Union or Confederate
captain, sergeant, or corporal as
you test you skill against the
computer or a friend.

SPOT
Run

SPOT, the cool 7-UP character
seen on soft drink cans and
advertisements everywhere, is
featured in a new release from
Virgin Mastertronic (18001
Cowan, Suites A & B, Irvine,
California 92714) appropriately
called SPOT the Computer Game
($29.99).

SPOT is a game as easy to
learn as checkers, yet it has lev-
els of complexity that will chal-
lenge chess players. Five
difficulty levels and the ability to
customize the play screen ensure
additional play value.

“SPOT has fun everywhere,"
says 7-UP brand manager Bart
Johnson. “‘It was only a matter of
time before he invaded
computers."

for the 64/128.

This 3-D mind teaser chal-
lenges you to maneuver falling
blocks within a three-dimensional

practice mode, and a save fea-
ture to store your favorite setup.

Also available from Califor-
nia Dreams is Vegas Gambler
for the 64/128. Try your luck with

Boys of Summer II

MicroLeague Sports Association (2201 Drummond Plaza,
Newark, Delaware 19711-5711) has released Enhanced
MicroLeague Baseball II ($39.95) for the 64/128. No minor-
league joystick game, this simulation forces you to think.
You win or lose based on your managerial decisions.

New features include enhanced ballpark graphics of
the Polo Grounds, Yankee, and Dodger stadiums, pop-up
screens for easy access to midgame statistics and substitu-
tions, expanded offensive and defensive options, pitching
and hitting stats against left- or right-handed batters, steal-
ing and base-running ratings, field averages plus throwing
range and arm strength, fatigue and power factors, and

more.

Enhanced MicroLeague Baseball II comes with a general
manager function, an automatic stat compiler, and 26 all-
time great teams. Look for MicroLeague Sports to release an
Owner’s disk, Stadium disks, Season disks, a League Leader
disk, and even World Series, Franchise History, and All-Star

disks in the future.

Publishing Power

atel Computers (3430 East

Tropicana Avenue #65, Las

Vegas, Nevada 89121) has

been named exclusive dis-
tributor for Handyscanner 64
and Pagefox, two products that
create a powerful desktop
publishing system for the
64/128.

Handyscanner 64 is the first
hand-held scanner for the 64.
Completely printer independent,
the unit will read graphics from
magazines, books, photographs,
or original artwork, which will
then appear in a digitized format
on the computer screen.

Utilizing an elaborate gray-
tone processing method, the
Handyscanner 64 promises ex-
cellent results for digitized color
or black-and-white photographs.
There are three processing meth-
ods, and the scanner has sepa-
rate control switches for light
intensity and contrast, which
help produce superior results
with difficult copies such as
photographs with little contrast.

Handyscanner 64 operates
independently of the computer
and requires only the included
interface for use with a 64 or
128 and any other paint or
graphics program. The software
interfaces with the Pagefox desk-
top publishing program module.

The unit sells for $299.95.

The second item distributed
by Datel is Pagefox, a desktop
publishing program with a
100K-memory storage-expansion
module. The program operates
via menus, mouse, or joystick to
define text, place pictures, and
control the total graphic editor.
Text can be placed in any area
and expanded or contracted to
eliminate the need to format
lines.

Ready-to-use layouts for
one, two, or three columns are
included, and text overflows
automatically into the next col-
umn in a user-selected sequence.
Text also automatically flows
around graphics. Frames can be
subsequently moved, enlarged,
reduced, or eliminated.

Text functions provide di-
rect entry of headlines, legends,
and so on through the keyboard
with any of 12 character sets.
There are eight variations of the
sets that can be formatted in any
combination for more than 3000
script possibilities such as italics,
shadows, outlines, and 3-D out-
lines. Additional character sets
are reloadable.

The Pagefox module, with
its 96K, plugs into the 64 or 128
expansion port; it costs $139.95.

Unlock the
Secret of
Maramon

MicroProse (180 Lakefront
Drive, Hunt Valley, Maryland
21030) will distribute The Keys to
Maramon ($39.95), Mindcraft
Software’s newest 64 release.

You're hired as the defender
of the island town Maramon.
Each night monsters attack the
city, and you must fight them. By
day, you gather equipment, sup-
plies, and information in town to
help you battle the creatures at
night. You won’t rest until all the
monsters are dead.

Choose to be either the
Huntsman, Courier, Blacksmith,
or Scholar, and use each charac-
ter’s unique strengths to win the
keys to the city, and your pay.

For What
Bugs You

Arlington Software (P.O. Box
916, North Arlington, New Jer-
sey 07032) has released the
Code Shadow Symbolic De-
bugger ($19.95) for the 64.
With its many features and
transparency, it can provide
a sophisticated environment
for debugging, testing, and
analyzing an ML program.

Complete symbolic ca-
pabilities are provided, from
assembling or disassembling
code to program-stepping to
addresses referenced in
command arguments. Sym-
bol tables from any assem-
bler can be imported into the
debugger, or the debugger
can generate its own coded
symbols. The program sup-
ports conditional break-
points, automatic code
patching, a watch window,
one-keystroke program freez-
ing, separate debugger and
application screens, anda
complete DOS manager.

The program, which is not
copy-protected, is RAMDOS
compatible and can load
into an REU, leaving virtually
all of its computer memory
free.

IE BIG BOY

GEOFFREY GOVE

reative Micro Designs (CMD)

has worked for years to improve

the user interface to Commodore

floppy disk drives and to im-
prove their performance. Now CMD
has taken the sum of its Commodore
disk drive knowledge and expertise
and condensed it into its
HD Series of hard drives
for the 64 and 128.

By doing so, CMD
hopes to extend the useful
_ life of the 64 and the 128
' well into this decade. After
having worked with a 20-
megabyte version of the
CMD HD Series hard
drive, I think CMD has an excellent
chance of doing just that.

Compatibility is the biggest hur-
dle to overcome when designing a
mass storage device for Commodore
8-bit computers. The 1541, the basic
Commodore disk drive, has a unique
way of formatting and storing data on
a floppy disk. Since the 1541 is con-
sidered the bottom line for the 64,
most software developers have chosen
to adopt its format in order to ensure
compatibility with the largest number
of machines. Unfortunately, the
1541’s 170-kilobyte storage capacity,
along with its limited data-transfer
speed, is considered inadequate by to-
day’s standards. p

ChaD

HD-20 Hard Drive:

COMPUTE G7

Interestingly enough, it was Com-
modore’s introduction of the double-
capacity 1571 disk drive followed by
the 800-kilobyte 1581 drive that re-
laxed the compatibility requirements.
This relaxed compatibility approach
was taken by CMD when designing
the operating system for its HD Series
of hard drives.

- BP ae

A Standard Design

CMD has chosen to design its HD Se-
ries around the SCSI standard. As a
result, although the storage capacity of
the basic HD drive can be as small as
20 megabytes, the system can be ex-
panded theoretically to a total of four
gigabytes (a gigabyte is 1,000 mega-
bytes, or more than a billion bytes)
spread over as many as 13 physical
hard drives. At the risk of having to
eat my words later, I will state that
four gigabytes is more online capacity
than any 64 user will ever need.

Physically, the HD is not much
larger than a 1581. The external di-
mensions of its all-metal case are 2.75
inches high, 5 inches wide, and 10
inches deep. The system is FCC certi-
fied to meet the limitations on radio
interference. Its external power sup-
ply, about half the volume of the HD,
is U/L certified and provides power at
5 volts, 12 volts, and — 12 volts.

The power supply has its own on/
off switch and is fitted with six-foot
long input and output cables. The HD
also has its own on/off switch on its
back panel. CMD recommends that
the drive be turned on and off via its
own power switch. The power supply
should be left on to extend the life of
the back-up battery for the HD’s built
in realtime clock.

The HD’s front panel is a flat-
membrane keyboard that sports eight
indicator lights and four push buttons.
The lights indicate power (on), activi-
ty (two lights), errors, and GEOS.
These are followed by push buttons
for SWAP8, SWAP9, and WRITE
PROTECT, each with an associated
indicator light and a RESET button.
In addition to their designated func-
tions, the lights flash through a diag-
nostic pattern whenever the HD is
powered up.

*

tons enhance the HD-20’s compatibil-

GB COMPUTE NOV

EMBER

ity with existing software. When one
of these buttons has been pressed, the
HD's serial bus device number is
changed, however, to the correspond-
ing value. If another disk drive set to
either device 8 or device 9 is already
connected to the serial bus, its device
number will be exchanged automati-
cally with the HD-20’s. The HD-20’s
default device number is 12. This can
be easily changed to any other device
number from 8 to 30 through software
control.

The HD’s back-panel connectors
include a four-pin power plug and a
pair of standard six-pin serial bus con-
nectors. The official capacity of the
Commodore serial bus is four devices;
however, I was able to run the HD-20
(device 12) on a 128 with a pair of
1571 disk drives (devices 8 and 9), a
1581 disk drive (device 10), anda
Xetec Super Graphix printer interface
(device 4) without any problems.

The remaining back-panel con-
nectors are unique to this drive. A six-
pin auxiliary port, which is physically
identical to the six-pin serial bus con-
nectors, is for future versions of the
operating system that will allow the
HD to intercept and store data being
sent to device 4 or 5 and then spool it
out to the printer.

Around, 14-pin, parallel port
connector is for the just-released
RAMLink parallel interface between
the HD and the 64/128. RAMLink
has space for up to four megabytes of
RAM and can be used to boost data-
transfer speeds between the computer
and the hard disk drive.

— 7" z

Daisychain

Last, but not least, a 25-pin SCSI con-
nector on the back panel lets you con-
nect up to six additional SCSI devices
to the HD-20. Since SCSI ports are in-
herently bidirectional, you can actually
use this connector to access the HD-
20 from another computer equipped
with a SCSI interface. Thus, it’s possi-
ble to utilize the hard disk drive in the
HD-20 with more than one computer
system. In order for this to work, each
computer has to be careful not to
trash the parts of the hard drive that
are used by the other system.

Inside the HD-20, the connection
between the system’s electronics and
the 20-megabyte Conner hard drive is
made via a standard 50-pin SCSI con-
nector and a short flat ribbon cable. If
you know what you’re doing, you can
daisychain additional SCSI drives to
the system by using the internal 50-
pin connector. Since there is no space

1990

inside the HD-20 for additional hard
drives, you’ll have to pass the ribbon
cable to the outside of the case. You’ll
also have to provide power and an en-
closure for the external hard drive.

Of course this setup will also vio-
late the HD’s six-month warranty and
will probably compromise the integri-
ty of the system’s radio frequency
shielding. Therefore, I do not recom-
mend this approach to the average
user, although I suspect that there are
plenty of hackers who will take advan-

tage of the available hardware.

The Operating System

Like all other Commodore 8-bit disk
drives, the HD hard drive is an intelli-
gent device with its own DOS in 16
kilobytes of ROM and its own 6502
microprocessor running at 2 MHz
with 64 kilobytes of RAM. In effect,
the HD is a stand-alone microcom-
puter. The input/output hardware
consists of a pair of 6522A VIA chips
and an 8255 chip. Most of the HD’s
DOS is actually stored on a small part
of the hard drive. The operating sys-
tem’s program code is downloaded
into part of the HD’s RAM when it’s
powered up.

By placing a part of the operating
system on the hard disk, CMD is able
to upgrade the system by simply send-
ing a floppy disk to the end user. In-
stalling the updated operating system
is a very simple process that takes
only a few minutes and does not affect
any of the data already stored on your
drive.

CMD has given a lot of thought
toward maintaining the compatibility
of the HD-20’s operating system with
existing 64/128 software. In general,
any software that does not rely on
disk-based copy protection and uses
any of the standard Commodore DOS
functions can be transferred to and
tun from the CMD hard drive. It’s
safe to say that any software originally
distributed on a 1541 floppy disk that
you've been able to copy successfully
onto a 1571- or 1581-format floppy
disk should run from the HD-20.

Native Partitions

The 20-megabyte capacity of the hard
disk drive cannot be accessed as a sin-
gle chunk. Instead, the HD-20’s oper-
ating system divides up the available
space into partitions. You can choose

from a variety of partition types, de-
pending on your needs. Native parti-
tions can be as small as 256 blocks (64
kilobytes) or as large as 65,280 blocks
(about 16 megabytes). They can store
more than 59,000 files, any one of
which can be as large as the entire par-
tition. Relative files in a native parti-
tion can have as many as 65,535
records. Native partitions also sup-
port true subdirectories similar to
those used with MS/DOS or Amiga-
DOS systems.

The HD also supports partitions
that mimic the 1541, 1571, and 1581
disk drives. These partitions have all
of the characteristics of the original
disk drives, such as storage capacity
and file-size limitations. The 1581
partitions even support 1581-style
subdirectories.

Compatibility with the various
drives has been maintained by sup-
porting all Commodore DOS func-
tions, including the various direct disk
access commands and the direct mem-
ory access commands. For 128 users,
the 1571 and 1581 burst-command in-
struction set is supported with the ex-
ception of the MFM formatting
commands, It would make no sense
to support the MFM formatting com-
mands because the drive medium in
the HD is fixed. CMD has even gone
so far as to emulate 1541, 1571, and
1581 job queue instructions.

To the 64 or 128, the HD looks
like a multiple floppy disk drive with
up to 254 drive units. Think of the
HD asa floppy drive with units num-
bered between 0 and 254. You do not
have to have 254 partitions, though;
just create as many as you want using
the provided software. The current
partition is the one that responds as
drive 0 to the 64/128. You can make
any partition the current partition by
issuing an instruction over the HD’s
command channel. You can also set
any of the partitions to be the current
partition when the drive is powered
up. Thus, any software that lets you
issue standard Commodore DOS
commands can access any of the HD
partitions.

It’s also possible to change the
current partition via the push buttons
on the HD’s control panel. But the
procedure is cumbersome, as it re-
quires the entry of the partition num-
ber as three binary digits using the
front panel’s indicator lights.

GEOS and CP/M
To use GEOS with the HD, replace

the one provided by CMD. You also
install the CMD HDTime program on
your GEOS boot disk, which lets
GEOS automatically set its clock from
the HD’s built-in realtime clock.
GEOS can only access 1581 partitions
on the HD. Thus, to GEOS the HD
looks like a 1581 disk drive whose
floppies are changed with the CMD
QuickMove utility. QuickMove also
lets you copy GEOS files between
1581 partitions on the HD. It’s also
possible to boot GEOS directly from
the HD. According to CMD, the May-
erick utility, available from Software
Support International, can be used to
install GEOS onto a 1581 partition.

If you have the May 28, 1987,
version of CP/M Plus 3.0, you'll be
able to access 1541, 1571, and 1581
CP/M partitions on the CMD. Note
that the 1581 CP/M partition can only
be accessed from CP/M, as it isn’t the
same as a standard 1581 partition.
Earlier versions of CP/M can only ac-
cess 1541 and 1571 partitions. As with
GEOS, CP/M treats the HD as another
floppy disk drive whose disks can be
changed under software control. The
SPORT.COM utility is a CP/M pro-
gram provided with the HD that is-
sues Commodore DOS commands
via the serial port. SPORT.COM is
used to swap partitions on the HD
under CP/M.

More Utilities
A set of generic utilities comes with
the HD in addition to specific utilities
for GEOS, CP/M, and QuantumLink,
These utilities include a versatile file
copier; a whole disk copier that can
duplicate a 1541, 1571, or 1581 floppy
disk into the corresponding HD parti-
tions; and a variety of partition and
HD system-maintenance utilities.
Most of these utilities come in both
128 and 64 versions. In general, the
utility programs are easy to use with
onscreen menus and built-in prompts.
Since the HD supports the serial
port’s burst modes, it works very well
with the 128. However, the 64 lacks
the burst-mode hardware, which lim-
its its data-transfer speed over the se-
rial port. CMD’s JiffyDOS greatly
improves the performance of the HD
with a 64. JiffyDOS consists of a re-
placement ROM chip for the comput-
er’s operating system. To install it,
you'll have to open your computer
and replace the existing ROM. You’ll
also have to replace the ROM in your
floppy disk drive. On the 128, sepa-
tate ROMs are provided for the 64
and the 128 modes. Replacing the

1ae9:=9).0

ROMs can be a problem if the origi-
nal chips in your particular model
are soldered in or if you aren’t famil-
iar with handling semiconductor
components.

Speed

Serial-port transfer speeds between
the HD and the computer are the
same as for a 1541 disk drive when
run with a stock 64. On a 128, transfer
speeds were comparable to a 1581. In-
ternal drive operations, such as for-
matting a partition, generally take
only a few seconds. Loading a 150-
block file from the HD, with Jiffy-
DOS, takes only 5 seconds. Saving the
same file to the HD, with JiffyDOS,
takes 19 seconds. Booting CP/M from
an HD partition requires only 24 sec-
onds. Copying a double-sided 1571
disk to an HD partition, using the in-
cluded MCOPY whole disk copy pro-
gram, requires only 74 seconds.
Copying a 1581 disk to an HD parti-
tion using MCOPY takes 81 seconds.

CMD has done an excellent job
of designing a SCSI hard drive inter-
face for the 64/128 computers. It has
addressed compatibility issues by pro-
viding both hardware emulation and
custom software. In general, the limi-
tations of the system are due to the
built-in limitations of the Commo-
dore operating system.

The HD series of hard drives is
intended for serious users of produc-
tivity software who can justify its cost.
In particular, Creative Micro Designs
has indicated that a number of bulle-
tin board programs will work with the
HD hard drives. GEOS users should
find the HD an effective tool. Keep in
mind, however, that the HD operates
as a collection of 1581 disk drives as
far as GEOS is concerned. A similar
limitation applies to CP/M users.
Also, be prepared to add JiffyDOS to
your system in order to obtain the
maximum possible performance from
the HD. ia}

Wait and See

I was dismayed yesterday when I
called the circulation department of
your magazine to find out why I had
not received my July issue. I was in-
formed that Gazette magazine was be-
ing combined with the parent
magazine. The primary reason I sub-
scribed to Gazette was that I wanted a
magazine dedicated to the Commo-
dore 8-bit computers and this was the
best one on the market. Now I fear
that if Commodore machines will
have to compete for magazine space
with other computers, there will be
fewer articles and programs for mine.
T have a 128. I will wait and see, but if
it is not the quality I have enjoyed and
grown accustomed to, I will sadly not
renew my subscription.

TIMOTHY GROSSER
COPPERAS COVE, TX

As a Gazette reader and subscriber
since December 1984 (still have em
all), it should make little difference as
to your choices in format, paper, bind-
ing, and so on. Gazette is Gazette is
Gazette. Whatever it takes to move
ahead into the nineties is OK. Con-
tent, not format is what is important
to me.

Autobooting

I was at a friend’s house (who has an
IBM), and when he turned on his
computer all the programs booted
automatically with something called a
CONFIG.SYS file. Is there something
for the 64 that can do this?

NICK D'ALONZO

COATESVILLE, PA

Your friend’s IBM probably has a
file called AUTOEXEC.BAT in the
directory of its default startup disk.
DOS automativally executes what-
ever commands are in this file
whenever the computer is switched
on. This command is often used to
load and run a commonly used pro-
gram. The 128 has a similar auto-
boot feature for 128 programs, but
it’s unavailable for the 64 or for use

with 64 programs. We did run a
program for the 128 called Fast
Boot (May 1987) that lets you insert
a disk in the drive, turn on the com-
puter, and have a 64 program ap-
pear on the screen.

A Jiffy Proofreader Tip

Iam a contented user of a 128D and
JiffyDOS, and I like to type in some
of the interesting programs you pub-
lish in your excellent magazine. In or-
der to use The Automatic Proofreader
with JiffyDOS, however, I find it nec-
essary to make two small changes to
the program since JiffyDOS alters the
vector found at 772 and the Proof-
reader checks this vector twice to
identify which machine is being used.
In lines 30 and 90, change IF VE =
17165 to IF VE = 61137. Earlier ver-
sions of the Proofreader have a differ-
ent line number but the same PEEK. I
hope this may save one or two readers
who have the same setup a few min-
utes of head scratching.

JO}

IRA
INMER, N.S.W
RALIA

Thanks for the tip and the kind
words, John. The JiffvDOS speed
enhancement system from Creative
Micro Designs does indeed alter the
vector you mentioned and could in-
terfere with the Proofreader. Those
of you using JiffvDOS installed on a
64 might want to make a similar
change in your version of the Proof-
reader. Change the value of VE in
line 20 from 42364 to 60004. Also,
check out the review of JiffyDOS 6.0
elsewhere in this issue.

Tree Tracing Revisted

In the June “Letters” column of Ga-
zette, we asked readers to help Roy N.
Kelley of Hamilton, Ohio, locate gene-
alogy programs for his 64/128. Dozens
of people wrote, and here are some of
their suggstions.

Monmouth, Illinois 61462, has share-
ware, FGS and PED C, $21.95, that

igree sheets. I have been using the
original for two years, and I like it
very much. An improved version is
also available.

Powerful Utilities

Most of the time machine language
programs conflict with each other in
memory, but I use three great ones si-
multaneously. First I load Quick! (De-
cember 1988), relocated to block 202.
Next, Function Key Magician (Febru-
ary 1988) goes in, giving me 16 tailor-
made function keys. One of these
loads my all-time favorite utility, Tri-
ple 64 (April 1985). I can now load
and edit three separate 25-block
BASIC programs quickly and effi-
ciently. That’s a lot of muscle for a
64! Thanks and keep encouraging
authors.

Del Gre Niet Ape ec!

{e)

t’s 5:00 a.m. It’s dark. My

daughter, Catie, and I have just

finished doing “her” paper

route. It’s a Tuesday morning,
and the routine never varies. Deliver
the papers. Feed Mowie the cat. Take
the trash out to the curb. Brew a fresh
pot of coffee. Now, steaming cup of
coffee in hand, I trudge up the stairs to
my study, where I spend many long
minutes staring with bleary eyes into
an empty computer screen.

Suddenly my fingers start to itch.
I feel a subliminal, submuscular trem-
bling begin to wriggle up my nerve fi-
bers. In anticipation, I place my
fingers on the keyboard. Miraculously
the fingers begin tapping, and words
appear magically on the computer
screen. The cursor flies across the
screen like a kite, sweeping across the
blue sky, uncovering clouds shaped
like letters, words, entire sentences.

I push away from the keyboard
and gaze fondly at the screen. Now
that’s real writing, I think admiringly.
I grab my empty coffee cup. Coffee
break time!

As I sit watching the steam rise
from my fresh cup of coffee, it occurs
to me how strange it is that we inter-
act with our computers by using a
keyboard. Think about it. Dancing
fingers. Ballerina fingertips that tap
and skip across the keys. Is this nor-
mal? Have we as a species spent mil-
lions of years evolving just for this
moment—so we could poke a few
keys and communicate with a
computer?

Isn’t there a better way?

We all know that computers re-
quire input through a keyboard be-
cause that’s the way they evolved.
Once upon a time (approximately 40
years ago), they were highly special-
ized beasts that required communi-
cation through special symbols—
originally numerical, later alphanu-
merical. First cables were used, later
switches on the computer’s front pan-
el. For a while computer punch cards
were in vogue. Finally it occurred to
someone that perhaps the simplest so-
lution was to just attach a QWERTY,

typewriterlike keyboard to the ma-
chines and have at it.

But it’s no longer the 1940s and
1950s, It’s 1990, and maybe it’s time
to look beyond keyboards. After all,
how many regular human beings actu-
ally feel cozy around a keyboard
anyway?

One of the most advanced com-
puters to grace the movie screen in re-
cent years was Johnny Five, the hero
of the two Short Circuit movies. John-
ny loved input. But did you ever see
him getting it through a keyboard?
Never. Instead he used his powerful
optical sensors (his eyes), auditory
sensors (his ears), and tactile sensors
(his fingers and hands) to gain his pro-
digious knowledge of the real world.

OPEN YOUR
MIND TO

COMPUTER

IMPLANTS

In addition, Johnny looked dis-
tinctly uncomputerlike. Instead of sit-
ting on someone’s desk meekly and
quietly waiting for the gentle tap of lit-
tle keys, he was rolling around cities
and forests, combing the countryside
for more input. “Input! Input!” he
cried. “More input!”

Johnny Five is a good example of
a computer that doesn’t look like a
computer. There are many more ex-
amples in everyday life. Take your car
or your wristwatch. Take your tele-
phone, your microwave, your video
camera, your CD, or your Walkman.
Or how about fax machines and
phone mail at offices? All these are
computers. Some still have keys, con-
trol panels, or buttons, but they accept
other forms of input as well—images,

voices, light waves, and so on.

As computer chips keep getting
smaller and more powerful, the pres-
sure will grow to transform desktop
computers into something totally
new. Already, incredibly powerful
computers can fit in a briefcase, on
your lap, or even in your pocket. A
new computer from Sony lets you
write on the computer screen with a
plastic stylus. A new touchscreen from
IBM lets you point at the screen and
abandon the keyboard entirely!

If computers keep shrinking, it
will soon get impractical to try to at-
tach a full QWERTY keyboard. For
many years experts have been predict-
ing that computers of the future will
be built right into our clothing—our
eyeglasses, our credit cards, our shirts,
even our underwear and socks.

In his award-winning book
Neuromancer, William Gibson specu-
lates that in the future computers will
become so small that they'll be able to
dangle from necklaces, hang from our
ears like earrings, or nestle inside of
fillings in our teeth. Gibson imagines
that human-computer interfaces will
evolve into small “terminals” im-
planted in our skulls directly behind
our ears. We'll carry small cartons of
microsofis—intelligent cosmetic jew-
elry that contains huge databases, new
skills libraries (like juggling or speak-
ing French), and antennae (cellular
phones the size of a sugar crystal).

Whenever we need to communi-

APROTEK MINIMODEMS”™

Reach Out and Touch Everyone!

There is an entire electronic world out there at the other end of your phone line.
It's a world you should find out about, because it's going to experience explosive

growth in the 1990's. It's the world of Electronic Information.

Right now, there exist huge databases filled with information of every imaginable
type. Electronic newspapers publish accurate accounts of events only minutes
after they've occurred! People send and receive E-Mail (electronic mail) messages
to and from each other, regardless of their physical location on the planet! People
are buying and selling things, paying bills, getting college educations, and even
working (called “Telecommuting”) from their own homes. And this doesn’t even

scratch the surface of what's coming.

Why wait any longer to join the Information Revolution? Especially when
Aprotek has just made it so easy for you to buy today! How? By giving you easy to
use high-speed modems at breakthrough prices! A modem is just a device that
allows your computer to talk to other computers over ordinary phone lines.

Modems come in different speeds. Right now, 2400 baud is the fastest speed that's practical for the dial-up phone system.

For the more experienced among you, the Aprotek Minimodems are completely Hayes “AT” command set and are 2400 baud
“ampersand command” compatible, auto-dial, auto-answer devices that auto-switch between 300, 1200, and 2400 baud for maximum
communications flexibility and service compatibility. Minimodems carry built-in sound capabilities (internal speaker on the RS-232 &
64/128 versions, monitor speaker on the Amiga version) and a full array of status indicator lights.

If you're new to telecommunications, don't let the terms above throw you - it’s just a technical way of saying that Minimodems will give

you every feature you could ever need in modem.

The C64/128 Minimodem plugs directly into the user port on the back of your computer. The Amiga version plugs right into the serial

port and comes with a builtin extension cable so you'll be able to use
it with an Amiga 500 or 2000 series and still be able to see the status
indicator lights. The Commodore version works onALL 64's or 128's
ever made, while the Amiga version works on the 500 or the
2000/2500 series of computers. A separate RS-232 and Amiga 1000
version is also available (please call for details).

The most exciting aspect of the Minimodems is the remarkable
prices! We've NEVER been able to offer this kind of sophisticated
power at prices so low before! Now there's no good reason not to get
involved in the Information Revolution today — and begin exploring
the world of tomorrow.

CONVERT-A-COM™

Convert your Commmodore direct-connect modem
for use on another computer.

Do you have or do you plan to get an Amiga, a PC or other computer?
CONVERT-A-COM will allow you to use your Minimodem-C or C-24 or
Commodore 16xx series modem with it, CONVERT-A-COM comes ready
to use with a 25 pin “D" style female connector that will connect to the
RS-232 serial port of virtually any computer. 9 pin "D” adapters, order
#3009, and gender changers, order #3025/M, are also readily available
through us for $5.95 each or through your local computer store.
CONVERT-A-COM will convert
your Aprotek Minimodem-C
or C-24 into a 100% Hayes
compatible modem to use with
your other computer. It will
also work with Commodore
16xx series and Lynker types,
but with their reduced Hayes
commandset. This unitis not
usable with an Anchor 6480
type modem because of soft-
ware inavailability.

USER-SWITCH™ new iter

Finally, for all you C-64 & 128 owners who have more than one device that
plugs into your user port, (and especially you ham operators), we have
your solution. USER SWITCH is a device which will allow you to attach
everything (up to 3) and simply select the one you want to use. We've

designed USER SWITCH so that pins B, C, D, E, F, H, J, K,L,M, 2 &3 are
switched. This gives you maximum compatibility because virtually all user
port devices use only
some or all of these
(Allothers are connect-
ed straight through.)
In most cases youcan
put any device on any
of the 3 port outputs.

A few devices may be
too bulky to plug into
port #3, so #1 or #2
can be used fora bulky
user port device.

THOM PS ON

eel like giving your 64 a frontal

lobotomy? Try this: POKE

1,PEEK(1) AND 253. You’ve

just removed your computer’s
intelligence. Hit RUN/STOP-
RESTORE to return your 64 toa
more productive state.

Experienced programmers will
recognize the above command as the
one that switches out the computer’s
ROM (Read Only Memory). Every
time your computer prints READY,
flashes the cursor, or complains about
your syntax, it’s because the instruc-
tions located in ROM told it to do so.
Without its ROM, your computer is
functionally brain dead.

Two ROMs. The 64 has two
types of ROM: 8K of BASIC ROM,
which is responsible for interpreting
and executing BASIC instructions,
and 8K of Kernal ROM, which han-
dles the computer’s more specialized
functions, such as reading characters
from the keyboard and moving the
cursor. Together they form the 64’s
operating system.

BASIC ROM is located at
40960-49151 ($A000-$BFFF), and
Kernal ROM is located at the top of
the 64’s memory map at 57344-65535
($E000-$FFFF). As you might expect,
reading one of these locations returns
the value that’s stored in ROM. After
all, that’s what the computer sees
here. However, when you switch out
ROM as we did above, RAM takes its
place. At this point, reading one of
these locations returns the value that’s
stored in RAM. Interestingly, values
written to these locations are always
stored in the RAM that resides here,
no matter what the in-out status of the
ROMis.

The reason your computer hangs
when you switch out ROM from
BASIC is because the underlying
RAM doesn’t contain any coherent
machine language routines for the
computer to execute. That is, not un-
less you put them there.

Customizing ROM. Because the
underlying RAM can be written to at
any time, it’s easy to move the con-
tents of ROM to the corresponding

RAM addresses. Once that’s accom-
plished, switching out ROM has no ill
effects. Best of all, you can now modi-
fy the ROM code to your liking, thus
changing the way the computer
behaves.

To copy ROM to RAM and then
switch out ROM, type in and run the
following program. Be patient; this
takes more than a minute to run.

10 FOR I=40960 TO 49151:POKE
I,PEEK(I): NEXT

20 FOR I=7344 TO 65535:POKE I,
PEEK(I):NEXT

30 POKE 1,PEEK(1) AND 253

Line 10 copies BASIC ROM, and
line 20 copies Kernal ROM. Line 30
switches out ROM by clearing bit | of
memory location | (the computer’s
R6510 register). Bit 0 of this register
controls BASIC ROM, while bit 1
controls Kernal ROM. You should
note that we simply clear bit | in line
30 because BASIC ROM is automati-
cally switched out whenever Kernal
ROM is. Only BASIC ROM can be
switched independently.

READY? Now that the dirty
work is done and ROM has been
moved into RAM, it’s time to have
some fun. To begin with, let’s change
the READY prompt. Enter POKE
41849,65:POKE 41850,78 after run-
ning the program above. A familiar
name should appear in place of the
computer’s normal greeting. If you

like, you can add these POKEs to the
end of the program above.

On the more practical side, disk
drive owners can force their comput-
ers to default to loading from and sav-
ing to device 8, the disk drive, instead
of device 1, the datasette. Enter
POKE 57818,8 and you won’t have to
type a ,8 after every load and save
command,

In an old issue of COMPUTE!
magazine, Jim Butterfield lists a
POKE that stops BASIC from shout-
ing ILLEGAL QUANTITY ERROR
every time you try to get the ASCII
value of a null string. Enter POKE
46991,5 and the computer will return
a value of 0 when you PRINT
ASC(*”).

Sheldon Leemon mentions
changing INPUT’s prompt character
from a question mark to a colon in his
book Mapping the Commodore 64.
Enter POKE 53846,58 to make this
change. Actually, you could POKE
the ASCII value of any character here,
such as a 32 for a space.

Enter POKE 61765,252 and BA-
SIC’s GET statement will wait until it
receives a valid keypress before con-
tinuing on (no more GET K$:IF
K$=“ ” THEN... commands).

Adventuresome machine lan-
guage programmers might go even
further and replace the 64’s ROM
code entirely. BASIC could be re-
placed with a Pascal interpreter, or the
whole computer could be converted
into a dedicated word processor or
database system.

Of course, switching out ROM
does make your computer more vul-
nerable to stray POKE commands. If
you accidentally destroy a sensitive
ROM location, your computer could
easily lock up. You can switch back to
the normal ROM by entering POKE
1,PEEK(1) OR 3 (assuming the com-
puter is still responding to your com-
mands), hitting RUN/STOP-
RESTORE, or turning your computer
off and on. Any mistakes (or improve-
ments) that you make while modify-
ing your 64’s ROM code are quickly
forgotten when the power goes out. ©

BEGINNER BASIC

LARRY COT OmIN

ast month, we began a program

that moves a musical sprite with

a joystick. Let’s continue from

the point where we placed a green
quarter note on a musical treble clef
staff.

We'll be able to play 41 notes,
from two octaves below middle C to
the fourth A above middle C. The 64’s
Programmer's Reference Guide pro-
vides the frequency values; from them
we calculate POKEable values. First
we must dimension the arrays.

200 DIMFU(41),FL(41),C(41)

FU() and FL( ) are the upper- and
lower-frequency arrays that will hold
the values to be POKEd into voice 1’s
frequency control registers. C( ) is the
array for the colors that correspond to
the musical notes.

Let’s read the 41 decimal values
and colors and calculate two POKE-
able values for each.

210 K=256:FORJ =41TOISTEP—1:
READD,C(J):FU(J)=INT(D/K):
FL(J)=D—FU(J)*K:NEXT

57743,6

Now we define JS, the memory
register for joystick port 2.

300 JS=56320

Lines 310-390 form an infinite
loop; the only way to break out is to
press the Run/Stop key or to turn off
the computer. First, PEEK at the joy-
stick port to see what value is there
(JD means Joystick Direction).

310 JD=PEEK(JS)

We need to check only for certain
values that correspond to particular
directions. To detect if the stick is
pushed up, enter

320 IFJD=126THENN=N—4:1FN
<49THENN=49

The note should move up when
the stick is pressed up. N is the verti-
cal position of the sprite on the screen
(see lines 110 and 180). N must be de-
cremented by four pixels for the sprite
to move up a note.

We limit the value of N to keep
the note on the screen. In this case,
the top line’s position has the value
N=49. Now look to detect a down-
ward press.

PROGRAMMING
WITH A

MUSICAL

OP RITE

330 IFJD=125THENN=N+4:IFN
>209THENN=209

In this case N is incremented by 4 and
the bottom line of the staff corre-
sponds to a value of 209 for N.

We haven’t moved the sprite yet;
we’ve only assigned it a new vertical
position. Let’s look at the port again
to detect a press of the fire button,
which will sound a note.

340 IFJD=111THENGOSUB400

Press the fire button and port 2

contains the value 111. We also want
to detect if the joystick is pushed up or
down with the button pressed. This
sounds notes as it moves, with gliding
arpeggios. GOSUB400 to play the
note, assign a new vertical position to
the sprite, and check vertical limits.

350 IFJD=110THENGOSUB400:
N=N—4:IFN<49THENN=49

360 IFJD=109THENGOSUB400:
N=N+4:IFN>209THENN = 209

Here’s where we actually move
the sprite to the new position N:

370 POKEV + 1,N:Q=INT(N/4—11)

V+1 is sprite 1’s vertical postion. Q is
a calculated index to the color array.
(Remember reading the color num-
bers in line 210?). The colors cycle
through seven changes, then repeat.

Thus all Cs are green, all Ds are
red, and so on. Now POKE the color
number into sprite 1’s color memory
register.

380 POKEV +39,C(Q)

End the main loop by returning
to its beginning:

390 GOTO 310

To sound the note, POKE voice
1’s frequency registers with the figures
calculated in 210:

400 POKES, FL(Q):POKES + 1,FU(Q)

Sand +1 are the first two registers
of the sound chip; they control voice
1’s frequency. We now turn on the
note in a rather strange way: by turn-
ing it off first. This, combined with
our envelope (defined in line 20), en-
sures that our notes can sound either
one at a time or as an arpeggio.

410 POKES + 4,64:POKES + 4,65
420 RETURN

When you run the program, try
playing a tune with the joystick. o

his month, we'll show how the

BIT command may be used to

perform certain tests. Here’s our

project: Given a 6502-based op-
code, we want to find out how long
the instruction might be.

A pattern in the opcodes allows
us to guess the length: If an instruc-
tion (in hexadecimal) ends with D, it’s
a length-3 opcode. But some patterns
are not that simple. Opcode $20 (JSR)
has length 3, code $30 (BMI) has
length 2, and code $40 (RTI) has
length 1. The test will need to be con-
structed carefully.

Standard disassemblers use a
lookup table to determine an instruc-
tion’s length.

The code that follows is more
compact, and it shows a new way to
use the BIT instruction.

Normally, a programmer would
examine specific bits by masking
them with AND and then performing
a comparison. To continue testing,
the original value would need to be
loaded again so that a new mask could
be applied. The BIT instruction has a
built-in AND test that doesn’t disturb
the values being tested. It’s more
efficient.

The following program runs on
all Commodore 8-bit computers. As-
sume that the opcode to be analyzed
is in the A register. It won’t be dis-
turbed during our analysis program; it
will still be there when we've finished,
and the length value will be in the X
register.

First, test specifically for the one
instruction that defies the pattern—
JSR, opcode $20, with a length of 3.

2045 LDX #$03 ;may be length 3

2047 CMP #$20 _ ;test for $20

2049 BEQ $2069 ;yes, so we're
done

Address $2069 represents the end
of our analysis. As you can see above,
we’ve preloaded X with 3—the right
value—so we can branch directly to
our completion address. Preloading X
makes for smooth coding.

Next, we test the opcode in A

against a fixed mask of $9F stored at
address $2081. (Wouldn’t it be nice to
have immediate-mode addressing
available for the BIT instruction?)

If none of the bits match, the Z flag
will be set. Mask $9F has six bits set.
The only instructions that will set the Z
flag are opcodes $00 (BRK), $40 (RTI),
and $60 (RTS). Value $20 would also
match, but we’ve already handled it.
When any of the length-1 codes are de-
tected, the program goes to $2069.

204B LDX #$01 ;may be length 1
204D BIT $2081 ;test against $9F
2050 BEQ $2069 ;exit if it is

MORE

BIT
NALYS

Now we test against a mask of
$08 stored at $2082. Only a single bit
is set in this number. Which opcodes
will it extract? If you wrote the opcode
in hexadecimal, you'd see that this
coding will identify all instructions
whose last digit (in hex) is less than 8.
Opcodes like $A2 (LDX), $30 (BMI),
$85 (STA), and dozens of others will
take this exit with length 2.

2052 LDX #$02 ;may be length 2
2054 BIT $2082 ;test against $08
2057 BEQ $2069 ;exit if it is

About half of the possible op-
codes now have been identified. Next,
we extract the codes whose hex repre-
sentation ends in 8 or A. We accom-
plish this by using a mask of $05,
which is stored at $2083.

2059 LDX #$01 ;may be length 1

205B BIT $2083 ;test against $05
205E BEQ $2069 ;exit if it is

All that’s left are opcodes ending
in (hex) 9, B, C, D, E, and F, Those
ending in B and F are not legitimate
instructions. The remaining opcodes
are length 3, with one important ex-
ception. An even first digit (in hex)
followed by 9 will be a length-2 in-
struction. For example, LDA immedi-
ate is coded as $A9. We can test for
this combination with a mask of $16.

2060
2062
2065
2067
2069

LDX #$02 ;may be length 2
BIT $2084 ;test against $16
BEQ $2069 ;exit if it is
LDX #$03 else set length 3
(analysis is complete)

The BIT intruction came through
with stunning elegance and efficiency, It
takes time and care to get the masks
correct and in their most efficient order.

In the accompanying BASIC pro-
gram, I’ve added a hex input routine
to precede the above code and a brief
output routine to follow it.

ONLY ON DISK

There's something new on the Gazette Disk. In addition to the type-in programs
found in every issue of the magazine, we're putting more features and programs on
the Gazette Disk each month. Often, these programs would be too large for readers
to type in. Check out the original 64 and 128 artwork on display in “Gazette Gallery,”
and look for our bonus programs as well. These programs and their instructions
appear only on disk. Here are descriptions of this month's bonus programs.

Bastion
Steve Harter

This challenging one- or two-player game is based on the popular arcade hit Star
Castle. Bastion is written entirely in machine language and features beautiful
vectored graphics. The object is to destroy an enemy spacecraft protected by a
multilayered force field.

Eyecatcher
Michael Lalonde

Eyecatcher is perfect for posting notices at user group meetings, school functions, or
Parties. Messages scroll across the top and bottom of the screen in huge letters
while a large clock displays the time in the center.

fter months of backbreaking
labor, digging at the base of

Pharaoh’s Pyramid, you've final-

ly uncovered the doors to eight
crypts that may lead to a fabulous
treasure. You check each crypt, but
there’s no treasure to be found. Has
the Pharaoh outwitted you?

You're not about to give up
before you’ve solved the Pharaoh’s
riddle. You're sure the entrance to the
pyramid is here, if only you can un-
ravel its key. You deduce that if open-
ing no single door provides access to
the pyramid and its hidden treasure,
then perhaps all of the doors must be
open before the secret entrance re-
veals itself.

As you set out to test your theory,
you’re surprised to find that the doors
are linked mechanically. Opening and
closing one door triggers a mechanism
in one or more of the others. There
seems to be a consistent pattern as to
how the doors are linked, but you re-
alize that you'll need luck, persistence,
and intelligence to open all doors.

Getting Started

Pharaoh’s Revenge is written entirely
in BASIC. Type it in using The Auto-
matic Proofreader; see “Typing Aids”
elsewhere in this section. Be sure to
save a copy after you’ve finished typ-
ing it in. When you're ready to take on
the Pharaoh, simply load and run the
program.

Playing the Game

Three challenging levels of play have
been included in the game. At the easy
level, all doors are connected in pairs.
Open one door and a second one
opens. If that second door is already
open, then it closes. At the difficult
level, each door may be linked to one,
two, or three others. Finally, the level
for superbrains requires you to pass
successfully through three tiers before
you can gain entrance. To open a spe-
cific door, just type the number that
appears above it. Depending on their
previous states, other doors associated
with it will either open or close.

The game keeps track of how

many moves it takes in your attempt
to gain access to the treasure. If you
get frustrated, you can close all the
doors at any time by pressing the A
key. If the Pharaoh’s curse proves to
be too much, press S to see the solu-
tion. The numbers of the key doors
will be highlighted in green. Enter
these numbers to solve the puzzle. If
you choose to look at the solution, the
treasure will, of course, elude you, and
the Pharaoh will have his revenge on
yet another treasure seeker.

PROGRAMS

rogrammers often use com-

mands and routines repeatedly in

their source code. Since Commo-

dore’s BASIC editor and the ma-
jority of assembly language editors
don’t have a cut-and-paste option,
you have to retype a lot of code. Well,
not anymore. With Ditto, you can
grab sections of code, partial lines, or
blocks of text and then copy them
elsewhere in your program.

Experiment with Ditto. You'll
find dozens of useful applications for
this versatile little program.

Getting Started

Ditto is written entirely in BASIC.
Type it in using The Automatic Proof-
reader. See “Typing Aids” elsewhere
in this section. Be sure to save a copy
to disk when you’ve finished typing.
When you're ready to use Ditto, sim-
ply load and run the program.

First, you’re asked if you want to
create a disk file. This option is used
for customizing Ditto. For the time
being, answer No, as we'll discuss cus-
tomizing later. You'll then see a mes-
sage that says Editor Activated. Now
you can load and edit a program or
begin to write one. Ditto is especially
useful when writing assembly lan-
guage programs. When using Ditto,
you have the following commands at
your fingertips.

fl Begin block define.
f3 End block define.
f5 Clear defined block.
f7 Copy defined block.

When you want to copy some-
thing, move your cursor to the begin-
ning of the block and press fl. Move
your cursor to the end of the block

bss

DAVID BRAY is ;

line 3. The default color is black, but
you can change it to any of the 64’s 16
colors by supplying a new value, rang-
ing from 0 to 15. Once you've entered
a new highlight color, run the program.

You are then asked if you want to
create a disk file. Answer Yes, and the
program saves a machine language
(ML) version of itself to disk with the
filename you specify. The new ML
version of Ditto can be loaded by typ-
ing LOAD“filename’”.8,1 and activat-
ed by typing SYS49152.

How It Works

As Ditto runs, it constantly checks for
keyboard input at vector 788 and 789.
When the fl and f3 keys are detected,

Ditto memorizes the entire screen to

and press f3. This defined block is keep the data intact. GM 101 SYS49152

then highlighted. Move the cursor to When f7 is pressed, the block is QB 49152 DenaeLAg cece 751,141,2

Customizing the Program This allows the Commodore editor to 234,193,88,169

To customize Ditto, first load the do the work of inserting lines when x3 49176 para an ' ase 7192,32,36

BASIC program and list the first few necessary. For example, ifyou add ER 49184 DATA 69,68,73,84,79,8

lines. The default highlight color is de- | something to a line that contains ap- 2,32,65

termined by the COLR variable in proximately 35 characters, an extra al KB 49192 DATA 67,84,73,86,65,8

line is inserted to hold the additional
data so it doesn’t overwrite the follow-'
ing line.

Ditto is designed to let a program-
mer copy segments from one line to
another. Although it will let you copy
large sections of text, the outcome
may not be as you had desired be-
cause when the copy takes place, the
Commodore editor is unable to deter-
mine where the line boundaries are,
causing some lines to wrap together.
This can be avoided by copying only
segments from one line to another. ~
Since the 64’s screen editor lets you
move to certain lines and change the
line number, there is no real purpose
in copying whole lines of text to an-
other section of a program.

When you want to deactivate Dit-
to, press Run/Stop-Restore. It stays in
memory, so if you want to reactivate
it, simply type SYS49152.

ometimes 80 columns just aren’t

enough. You may want to print a

spreadsheet or other document,

but it won’t fit on an 80-column
printer. It’s too wide. You could print
it smaller if your printer supports con-
densed type, but that’s not always the
best answer. For times like this, you
need Right/Side.

Right/Side is a sideways file
printer for sequential files. It’s de-
signed primarily to be used with
SpeedScript for printing word proces-
sor files and charts that are up to 255
columns wide. It’s also handy for
printing addresses on large manila
envelopes that have to be fed vertical-
ly into narrow-carriage printers.
Right/Side should work with all odd-
numbered Commodore and compati-
ble dot-matrix printers such as the
Okidata 120 and the Star Gemini II.

Typing It In

Right/Side consists of two programs.
The first program is written in BASIC.
To ensure accurate entry, use The
Automatic Proofreader. See “Typing

you've finished, be sure to save a copy

The second program is written in
machine language. To enter it, you'll
need to use MLX, our machine lan-
guage entry program (see “Typing
Aids”). The MLX prompts, and the
values you should enter, are as
follows:

Starting address: C000
Ending address: C157

When you've finished typing, be
sure to save a copy of the program
with the filename RIGHT/SIDE.ML
before you leave MLX. When you're
ready to use Right/Side, simply load
and run it as you would any BASIC
program.

Using the Program

When creating a sequential file for
Right/Side, the margin for the right
side of the text will be printed at
what’s normally the top of the paper.
In SpeedScript, set the right margin to

your choice of widths up to 255. If
you choose a number that is more
than the length of the longest line, the
printer will space down that number
of lines, The maximum number of
lines Right/Side will print is 80, the
normal printer width. The left margin
should be set to 0.

Before you can use Right/Side,
you must first convert your original
file or document to a sequential file.
To do that from SpeedScript, press
Shift-Ctrl-P, then press D to print
your document to disk as a sequential
file. Next, load and run Right/Side.

When the Right/Side menu ap-
pears, you must first select fl, Create
Right/Side File, to convert the se-
quential file into a Right/Side file. En-
ter the name of your sequential file
and then the name of the file you'll be
creating. The letters R/S are added
automatically as a prefix to indicate to
the program that this’is a Right/Side
document. Press Return on a blank
line to return to the main menu.

To print your file sideways, sim-
ply choose f2, Print Right/Side Files,
and enter the name of the newly creat-
ed Right/Side file. You don’t have to
include the R/S prefix—it’s added
automatically. Next, choose between
normal density (draft mode) and high
density (NLQ mode); then press any
key to start printing. To stop printing,
press and hold the space bar.

ank Shootout begins with two

hostile armies lined up like

pieces on a chess board. Instead

of an open space between these
opposing forces, the field is filled with
numerous obstacles that block the ar-
mies’ field of fire. Across the bottom
of the screen, a row of missiles waits.

You command one army, and
your opponent controls the other. The
object of the game is to maneuver
your forces around the obstacles and
capture the enemy command post.

Each player starts with a force of
ten tanks, 11 soldiers, five rockets,
and a command post that resembles a
castle. Once you start a soldier or tank
moving, it will continue until it strikes
an obstacle. Ifan enemy piece is with-
in range, your soldier or tank will
automatically fire at it.

Getting Started

Tank Shootout is written entirely in
machine language. Enter the program
with MLX, our machine language en-
try program. See “Typing Aids” else-
where in this section. When MLX
prompts you, respond with the values
given below.

Starting address: 0801
Ending address: 1A80

When you’ve finished typing in the
data, be sure to save a copy to disk
before exiting MLX.

Although it’s written in machine
language, Tank Shootout loads and
tuns like a BASIC program. When
you and a friend are ready to play,
plug a joystick into each port; then
load the program and type RUN.

Into Battle

Before starting the game, the two play-
ers should agree on whether to play
until one of the command posts is de-
stroyed or until one of the players
loses all of his or her pieces.

To play, use the joystick to move
your flickering rectangle until it cov-
ers the piece you want to move. Press
the fire button and hold it down while
you move the stick in the direction

you want the piece to move. Hold it in
that direction and then release the fire
button. The piece will move on its
own until it strikes an obstacle or
reaches an edge of the screen. To halt
a piece, put the rectangle on it and
press and release the fire button.
Please note that pieces will shoot
automatically when they meet an ene-
my. (If a piece does not shoot when
you think it should, look closer; you
will find that the enemy piece is out-

side your piece’s field of fire.)

The tanks can move and shoot in
all four directions. The soldiers can
move in all four directions but can
shoot only left and right. (Soldiers are
still dangerous because they fire much
faster than the tanks.)

The rockets work in a different
manner. Once you’ve ordered them to
move with the joystick, they will only
move up. Once launched, they will de-
stroy any piece in their path, friend or
foe. They continue until they hit a
wall and explode or until they hit the
top of the screen. Be extra careful with
the two missiles that are located be-
neath your army. Generally, you
should use those two as a defensive

measure and only as a last resort.
Soldiers will take 5 hits before
dying. Tanks will take 15, and rockets,
25. The command post is the weakest
piece. It will explode with the first hit.
If you are playing to destroy command
posts, plan carefully how to defend
yours. You can start a fresh game at
any time by tapping the Restore key. 5

AUTO PROOFIEADETe

The Automatic Proofreader helps you
type in program listings for the 128
and 64 and prevents nearly every kind
of typing mistake.

Type in the Proofreader exactly
as listed. Because the program can’t
check itself, type carefully to avoid
mistakes. Don’t omit any lines, even
if they contain unusual commands.
After you’ve finished, save a copy
before running it.

Next, type RUN and press Re-
turn. When the program displays the
message Proofreader Active, you’re
ready to type in a BASIC program.

Every time you finish typing a
line and press Return, the Proofreader
displays a two-letter checksum in the
upper left corner of the screen. Com-
pare this result with the two-letter
checksum printed to the left of the
line in the program listing. If the let-
ters match, it’s almost certain the line
was typed correctly. If not, check for
your mistake and correct the line.

The Proofreader ignores spaces
not enclosed in quotation marks, so
you can omit or add spaces between
keywords and still see a matching
checksum. However, spaces inside
quotes are significant, so the program
pays attention to them.

The Proofreader does not accept
keyword abbreviations (for example, ?
instead of PRINT). If you use abbre-
viations, you can check the line later
by LISTing it, moving the cursor back
to the line, and pressing Return.

If you’re using the Proofreader on
the 128, do not perform any GRAPH-
IC commands while the Proofreader is
active. When you perform a com-
mand like GRAPHIC 1, the computer
moves everything at the start of
BASIC program space—including the
Proofreader—to another memory
area, causing it to crash. The same
thing happens if you run any program
with a GRAPHIC command while
the Proofreader is in memory.

Though the Proofreader doesn’t
interfere with other BASIC opera-
tions, it’s a good idea to disable it
before running another program. The
simplest way to disable it is to turn the
computer off then on. A gentler meth-
od is to SYS to the computer’s built-in
reset routine (65341 for the 128,
64738 for the 64). These reset routines
erase any program in memory, so be

sure to save the program you're typing
in before entering the SYS command.
When using the Proofreader with
another utility, disable both programs
before running a BASIC program.

Each month, Gazette publishes pro-
grams for the Commodore 128 and
64, Each program is clearly marked by
title and version. Be sure to type in
the correct version for your machine.
All 64 programs run on the 128 in 64
mode. Be sure to read the instructions
in the corresponding article. This can
save time and eliminate any questions
which might arise after you begin
typing.

We regularly publish two pro-
grams designed to make typing easier:
The Automatic Proofreader, for
BASIC programs, and MLX, for en-
tering machine language programs.

When entering a BASIC pro-
gram, be especially careful with
DATA statements, as they are ex-
tremely sensitive to errors. A mis-
typed number in a DATA statement
can cause your machine to “lock up”
(you'll have no control over the com-
puter). If this happens, the only re-
course is to turn your computer off
and then on, erasing what was in
memory. This could cause you to lose
valuable data, so be sure to save a pro-
gram before you run it. If your com-
puter crashes, you can always reload
the program and look for the error.

Special Characters

Most of the programs listed in each is-
sue contain special control characters.
To facilitate typing in any programs
from Gazette, use the following listing
conventions.

The most common type of con-
trol characters in our listings appear as
words within braces: {DOWN}
means to press the cursor-down key;
{5 Spaces} means to press the space
bar five times.

To indicate that a key should be
shifted (hold down the Shift key while
pressing another key), the character is
underlined. For example, A means
hold down the Shift key and press A.
You may see strange characters on
your screen, but that’s to be expected.
If you find a number followed by an
underlined key enclosed in braces (for
example, {8 A}), type the key as many
times as indicated (in our example,
enter eight shifted A’s).

If a key is enclosed in special
brackets, K 9, hold down the Com-
modore key (at the lower left corner of
the keyboard) and press the indicated
character.

Rarely, you'll see a single letter of
the alphabet enclosed in braces, This

can be entered on the Commodore 64
by pressing the Ctrl key while typing
the letter in braces. For example, {A}
means to press Ctrl-A.

The Quote Mode

Although you can move the cursor
around the screen with the Crsr keys,
often a programmer will want to
move the cursor under program con-
trol. This is seen in examples such as
{LEFT} and {HOME} in the program
listings. The only way the computer
can tell the difference between direct
and programmed cursor control is the
quote mode.

Once you press the quote key,
you're in quote mode. This mode can
be confusing if you mistype a charac-
ter and cursor left to change it. You'll
see a graphics symbol for cursor left.
In this case, you can use the Del key
to back up and edit the line. Type an-
other quotation mark and you’re out
of quote mode. If things really get con-
fusing, you can exit quote mode sim-
ply by pressing Return. Then cursor
up to the mistyped line and fix it. If
the mistake involves cursor move-
ment, however, you must press the
quote key to reenter quote mode.
